Stability and Adaptability Patterns of Chilli Hybrids in Karnataka State

Chilli is an important vegetable and spice crop in India. It is most widely cultivated in India for its pungency and export-oriented quality. It is a climate dependent sensitive to various pest and disease infestation. The southern parts of the country emerged as novel diversity in the cultivated species the genus Capsicum. Investigations were carried out to assess the stability of many chilli hybrids using popular commercial checks across the nation. The results of these studies were meticulous and the popularity of hybrid chilli crop mostly depends on the yield and yield attributing factors. Breeding for most stable chilli hybrid needs genetic variation and the variance environmental factor plays a vital role in emergence of stable chilli hybrid. Considering all the edaphic factors and stability parameters the test hybrids were developed and evaluated at different environmental conditions. The test Hybrids, developed were subjected to various observations such as average fruit weight, fruit width, length, number of fruits per plant, etc., the best yielding genotype among different test hybrids, having higher yield level than the check and which were also stable for most of the characters as evident from their non-significant s2di values were considered for their adaptability. The adaptability of these selected hybrids for specific location may help in identifying most promising hybrids for yield and its component traits and to assess its stability across the state.
